Case Studies: Machine Learning for Materials Research

basic information

【Case Studies】 ■ In the prediction of the glass transition temperature (Tg) of polymers included in the bicerano dataset, the prediction model using customized polymer descriptors significantly reduced the root mean square error (RMSE) from 38K to 11K compared to using general descriptors. ■ A model was constructed that can accurately predict the 29Si NMR chemical shifts of silicon nitride using periodic three-dimensional descriptors. ■ A model using 140 descriptors based on chemical composition and structure accurately predicted the bulk modulus of 1181 inorganic crystals (over 60 elements) with high precision (R2=0.913). ■ The band gaps of 3000 transparent conductive oxides included in the NOMAD 2018 Kaggle challenge were accurately predicted by a deep learning prediction model built using 10 SOAP-PCA 3D descriptors and AutoQSAR/DeepChem. ■ A deep learning prediction model capable of predicting the water solubility of 8773 molecules collected from literature was constructed using AutoQSAR/DeepChem (R2=0.88). *Please feel free to contact us.
